Invalid Character In A Base-64 String?

Dec 15, 2009

Ok, so I got everything working except for one thing. My program stores text in a settings files (which it saves to and encrypts to wonderfully), but it will only work once. For example, I type in an author, title and body, and click Publish, it publishes and is labeled with a "1.". Restarting the application, you get the desired effect, a decrypted string from the encrypted settings file, now publish another entry, this makes a new line with "vbNewLine" and then encrypts it, fine and dandy. Now apon opening the application again, you get an error stating "Invalid character in a Base-64 string.". What do I do?

Encryption Code:
Public Function psEncrypt(ByVal sInputVal As String) As String
Dim loCryptoClass As New TripleDESCryptoServiceProvider

Getting An Invalid "Invalid Length For A Base-64 Char Array"?

Sep 9, 2011

where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.

Private Sub GetReport()
Try
Dim hawbs As String = String.Empty[code]....

The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.

Invalid Length For A Base-64 Char Array?

Sep 7, 2011

My program gets an encrpyted query string ,decrypts it and then pulls the pdfs in a popup window depending on the values in the string. The issue I am having is I have around 500 ids that I am passing whose pdfs need to be generated, but I keep getting the "Invalid length for a Base-64 char array".

Not sure what I need to do, I have read through the solutions and have done whatever has been said, with replacing the blank with the "+" but I cannot get this to work.

VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters

[Code]...

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

Invalid Connection String When Using Table Adapter?

Jan 17, 2011

I'm trying to use variables in my connection string to a table adapter. The only clean cut method I've seen is the following, however, I'm getting "Invalid Connection string" upon run-time. I'm assuming maybe this can't be done?

Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'BCPM_DDBODataSet.LTC_FBS' table. You can move, or remove it, as needed.

Modifying String Containing Invalid NTFS Filename

May 6, 2009

I have a piece of code to debug. Because of unknown bugs it creates a dummy filename. I want to track all the pieces of code who fires that creates the dummy filename, so I can change the dummy file creation to a thrown exception. Since I the dummy filename is stored on a string, I plan to modify that string to contain an invalid NTFS filename, maybe containing invalid chars. Is there a reason to prefer some invalid chars over others? There are some predefined invalid NTFS filename destined to this purpose? (I may think of AUX , COM1 , LPT1 or PRN , but those names run the risk of start sending data to a port instead of throwing an exception).

VS 2008 - Apparently Invalid Connection String

Mar 20, 2009

Before I explain, the connection string I am trying to use is copied directly from elsewhere in the application that has always worked and still does.
Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=|DataDirectory|cdb.rmd;
Persist Security Info=False;

My problem is that no matter if I go to "Server Explorer", "Data Sources", or any other option it will not let me add a datasource/database. Up to this point I have done everything at runtime but now due to reporting issues I need to create a dataset in design view.

This is what happens:
I click "Add connection..."
I choose "Microsoft Access Database File" (Which it is...)
I click "Continue"
Form shows up with a field for my connection string, which I insert (shown above).
I click "Ok"

I get the following error:
Format of the initialization string does not conform to specification starting at index 0.
The "Test Connection" button is apparently useless as the connection passes even if the field is blank.

I have attempted reducing the connection string to only what is absolutely necessary.
I have copied the string directly from connectionstrings.com replacing my filename.
I have renamed the file to an .mdb extension.
I have used the full path from C: all the way to the file.

I have written this code and tried running it but I am getting errors in the code segments below.

ICCPtotcircuitres is also returning 'nothing'.

VS 2008 .DBF Connection String - Invalid File Path?

Sep 21, 2009

Dim dbconn As OleDbConnection
Dim DBCommand As OleDbDataAdapter
Dim DS As New DataSet
dbconn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:COLORsitedataCUFORHDR.dbf;Extended Properties=dBASE IV;")

[Code]...

I prefer SQL server but im afraid in this app I have no choice. I think the .DBF file is v III dBase according to a thrid party .dbf viewer. The code explodes on the DBCommand.Fill(DS) line, telling me I have provided and invalid file path. The path is good to go.

Should I be using a driver with a different provider? When I remove the Extended Properties parameter I get an error unrecognizable database format - hinting in this case the path is correct.
